Hi,
First of all i am running "EasyOPC-DA.Net Demo Application", under the Machine Name text box, i have entered our live opc server (implemented with DA 2.0) e.g. 192.168.128.10, then after pressing the browse servers button there is a pop-up box showing opc operation failed. And the box display "No such interface supported". Do you have any ideal if the demo is able to connect to live opc server? I have tested other client such as the one supply Prosys which is able to access the opc group and item.
I have attached a screenshot of the error.

thank you

Re:

may i know is there any limitation on your trial version?

As stated next to the download link: "The trial provides valid data to client application for 30 minutes; after that period, the component needs to be re-started."
In general, QuickOPC looks well suited for the task you have described.
Best regards

Subject: Enquiry about Demo
Dear Sir/Mdm,
I have downloaded the QuickOPC-Classic 5.11 and try to run the sample demo applications but was unable to connect to my opc server. Do you have any idea why? I am trying to test the .net plug in, may i know where can i download a copy of api complete guide to use your api. I have to apologize, i am very new to opc and donet as well. And may i know is there any limitation on your trial version?
My application will need to read the temperature and some parameters from my opc server and perform calculations and automate certain task. And the opc server is implemented in DA 2.0 compliance code. And i am looking for a opc client that can simplify my task rather than writing codes to communicate with the opc automation dll.

thank you
regards
ch.
